what brand

Hi im new to this site but not to dirt bikes. I just want your opinion on what brand of 85 i should race. Im 5'4 and way in at 107 pounds. Im a really aggresive racer. I love speed and im particulary good when it comes to corners as thats how i win my races. whats the best 85 stock and modified for a kid that wants to win and race hard. Right now i have a suzuki and i hate it its done up somouch all it does is fall apart now.
